Hmm, okay, so this is sort of new. Bleeding-edge new. :)

Fujitsu MAV2073RC 74GB 10,000 RPM 8MB Cache Serial Attached SCSI (SAS) Hard Drive, OEM, $639

http://www.newegg.com/Product/Product.asp?Item=N82E16822116156

Features:
* Mean-time-between-failure (MTBF) of 1,400,000 power-on hours
* The industry's first 2.5-inch small-form-factor serial-attached SCSI (SAS) interface
* Native Command Queuing, providing faster execution of operation commands
* Uses smaller connectors and cables than U320, a benefit acknowledged by the SCSI Trade Association (STA)

--------------

But for high-speed access, smaller is better since the head-arm doesn't have to cover such a large area, and can be lower mass for greater movement speed:

Average Seek Time: 4ms
Average Write Time: 4.5ms
Average Latency: 2.99ms

A smaller platter also means they can spin it faster for even higher throughput. Once this technology has had time to mature it may eventually move up to 20,000 RPM platters.
